Its hard to say exactly due to weather differences (I wasn't correcting
my times to standard then) but before the Gibson I was usually running at
about 15.5 or 15.6, then after I ran at about 15.2 or 15.3. A couple of
tenths for sure, maybe a few tenths. Of course, the gains will be
dependent on other mods too; at the time, I had the MP PCM, FABM,
and a 180 degree t-stat. Once I get the JBA headers installed, I
expect the Gibson will help to augment them too. (I'll probably get
more horsepower out of the headers than I would if I still had the
restrictive stock exhaust.)
